MGLD FOR CONCRETE SIGN-POSTS.

Specification of Letters Patent.

Application filed June 24, 1908.

Patented March 16, 1909.

Serial No. 440,074.

To all whom it may concern.

Be it known that I, LEO G. HAAsE, a citizen of the United States,residing at Pasadena, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Moldfor Concrete Sign-Posts,of which the following is a specification.

The main object of the present invention is to )rovide an improvedmolding means where y the molding of such. cement posts is expedited andcheapened.

Informing sign posts as for use upon street corners and other places, itis very desirable that the be formed from material that can be readi yprovided with sign or other indicating characters and also that theposts will be lasting or not readily destroyed by the elements.

It has been found that metal is liable to rust and decoloration whenexposed to the weather, or it is too costly, when formed with sufficientstrength and rigidity, to ada t it for use in all places, and. it hasalso een found that wood is too liable to decay when buried in the earthto provide a desirable means for forming a sign for streets androadways. On the other hand I have discovered that a very neat anddesirable sign post can be formed from cement with the names of thestreet, or other information, made a permanent part thereof at the timethe post is made, either in the same or of a different color to rendersaid name more easily distinguishable.

The accompanying drawings illustrate a street sign made in accordancewith my invention, and also the means for constructing the same.

Figure 1 is a perspective view of one form of. 0st or street sign madein accordance wit my invention. Fig. 2 is a transverse sectional View ofthe mold or former with a post therein. Fig. 3 is a similar view of themold with part of the side removed. Fig. 4 is a longitudinal sectionalview ofthe mold Without the other side pieces. Fig. 5 is a sectionalview of the post resting upon the trough, after the front pieces havebeen removed.

Referring more particularly to the drawings, which are for illustrativepurposes, and, therefore, are not drawn to any particular scale, 1indicates a post made in accordance Withmy invention which may be or"any desired size and height, it being shown substantially square incross section and of a convenient height for placing it upon or adjacentto the corner of a street or sidewall 2. The post 1 is formed fromconcrete or similar plastic material and has its upper end pro videdwith letters or clurractcrs to indicate the streets, as Oak street andElm street, respectively. These letters or characters can be formed inthe sides of the post in any desired manner, they beiir shown as 1raised letters located within a sunfien field 3.

But it is evident that they could be formed to project from or be sunkenin a plain field or surface without departing from the spirit of myinvention.

In forming a street sign or post as above described, I prefer toconstruct a substantially rectangular box or receptacle from lower orfront side pieces 4 and rear or top pieces 5, as shown in '2. The moldor former is preferably held in itsrece )tive position by means of acradle formed from two base pieces 6, 6, which are held together bymeans of a clamp, as a-bolt 7 and handle nut 8. The inner or adjacentfaces of the base pieces are inclined, as shown at 9, and preferablyprovided with teeth or projections 10 for enga ing with the side pieces4 and holding t Lem against slippage.

The upper side )ieces are loosely mounted upon the lower si e pieces andheld thereon in any suitable manner, pins 11 being shown which extenddown into perforations 12 in the side pieces 4, and also latches 13which are pivot-ally secured to the blocks 6, 6, by bolts or pins 14.The adjacent edges of the side pieces are in actual contact except theupper edges of the top side pieces 5 which are preferably located at aslight distance from each other, as indicated at 15, and said edges arepreferably curved as shown at 16 to give a rounding appearance to thecorners of the post as shown at 17. The side pieces 4 are preferablyformed substantially as open frames with their inner faces channeled orre cessed, as shown at 18, within which are mounted the dies or matricesi9 for forming the letters or other insignia for giving the desiredinformation. The matrices 19 rest on the shouldered portions of thebottom mcmhers, as shown, so that said matrices can be removedtransversely to the planeof said bottom members. This construction hascertain advantages over a construction wherein the matrices areremovable by slid-:- ing them parallel to the plane of the mold members,as they can be more quickly removed and replaced. The matr1ces 19 arepreferably formed in sections, as shown at 20 in Fig. 4, with thedesired characters formed u on a portion of them as shown at 21 in Fig.4, and the others left plain. A suitable cap or end piece 22 is providedfor the mold or side pieces with its inner face formed into any desiredshape so as to register with the the post, according-to the place thepost is to occupy, and said side pieces are then laced longitudinallywithin the clamps 6. efore placing thematrices in the frames or sidepieces 4, the cavities therein, when it is desired to form raisedletters, as in the present instance, are filled with plastic material,as

cement, which is preferably of a difierent. color from that of theremaining portion of the 0st so as to be more cons icuous. Af-

ter t e matrices have been fille in this manner and the side piecesplaced in the clamp to form a trough like rece tacle, as shown moreparticularly in Fig. 3, t e trough is then filled with the material,from which the pot is to be formed, substantially even with the up er'edges of the trough or extending asuita le leces distance above thesame. The side are then-placed in position upon the sides 4 and securedas shown in Fig. 2, whereby an inclosed cavity is formed with a slightopening left at the u per edge between thetwo upper edges of t e samethrough which the rest of the material can be inserted to completelyfill the mold or cavity and thereby complete the post. After thematerial, as cement, which I prefer to use, and which may be formed inaccordance with any desired formula, is allowed to set or harden, themold is then removed by taking out the bolts 11 and swinging the latches13 down into the position shown in Fig. 3. A temporary trough likestructure '26 is placedupon the post in place of the side pieces a andthe post and trough are then inverted as shown in Fig. 5, and the clampsan side pieces 4 removed. The trou position for retaining the post bymeans of suitable supports or cradles '27 After the post has remained inthis position the desired length of time for the material to becomethoroughly set and hardened, the po t this manner it can -consistingoftwo bottom members, cradle gh 26 is held in its upright is' ready tobe taken to the place it is to be used and inserted in the ground orotherwise properly secured. By constructing a post in e made as solidand indestructible as rock itself and the desired characters can beformed upon or within it as readily almost as the post could be formedwith plain sides without such characters. As there will be no metalabout the post to discolor the surface, the characters upon the postwill always be plain and distinct, and as the elements can not possiblyafiect the post, the requirement of painting or otherwise rotecting thepost, as is necessary w th metal and wood, Willbe entirely avoided, andas the ortion of it that is buried within the ground is not affectedmoisture or otherwise, there will never be any occasion for replacingthe post witha new one except in case of actual breakage of the portionthat 5 extends above the ground.

Having described my invention, I claim 1 In a mold for forming signposts from plastic material, basev pieces having their upper endsinclined an serrated, a clamp for holding said base ieces in en port'position, a substantia y rectan ar mol sugiported on said base pieceswit two of its si es engaged with face pieces and provided with meansfor forming characters on the post, upper side pieces detachably securedto the lower side pieces and having their upper edges at a distance fromeach other to form an openin longitudinally ofthe mold, and a cap pieceor the mold.
